TECHNICAL MAINTENANCE
DISCONNECT THE UNIT FROM POWER SUPPLY BEFORE
ANY MAINTENANCE OPERATIONS!
Maintenance means regular cleaning of the fan surfaces from dust and dirt. Use a soft dry brush or a vacuum cleaner to remove dust.
The blades require thorough cleaning once in 6 months.
The filter prevents the fan soiling and reduces the cleaning periodicity. To clean the fan undo the self-tapping screws and remove the
fan cover. Clean the impeller blades with a cloth wetted in water and mild detergent solution. Avoid liquid dripping on the motor! After
cleaning the impeller, install the cover back and tighten the screws.
